Question:
My spindle is who cares F is welded to a bar,B is 1,5 inches diameter .5 inch long , c is .995 inch diameter and runs 3 inches from B to the threads of the retaining nut E without any size change just threads and that is it NO bloody D and E is the same size just threaded . So what hub do you have that fits that ? And why when I have selected trailers do you ask me about car models ? As for my trailer year old, make god knows, markings none .

Hey Bob, you doing okay? It sounds like you've been searching for a while and are pretty frustrated at what you're seeing (or not seeing for that matter).
The closest thing I can match your specs to is a BTR spindle like part # TRU44FR which has a grease seal with a 1-1/2" inner diameter, and then it uses L44649 inner and outer bearings, but they have a 1.063" inner diameter which is a little different than what you found.
If you remeasure your spindle at the "C" location and find it to be closer to the 1.063" diameter then you should be able to use the 4 on 4 Bolt Pattern # AKIHUB-440-2-EZ-2K or the 5 on 4-1/2" Bolt Pattern # AKIHUB-545-2-LFEZ-2K to get you back up and running.
If that measurement is still 0.995" then it sounds like you have a Frankenstein of a trailer that was hobbled together to get a job done (my dad has done this before) and you'll need to upgrade or modify some parts so the trailer uses industry-standard equipment that's easier to find. For example, you can have an experienced welder cut off your current spindles and then weld on the spindle I referenced above so you can use one of the hubs I mentioned.
We ask about vehicle year/make/model because a LOT of questions we get in have to do with parts that fit vehicles so if we can get that info early then it makes finding the right part easier for us, which then is easier for the person we're trying to help out.

Hey Bob, how did things turn out with the BTR spindle and hub options you were looking at? Were you able to confirm that C measurement and find a hub that fit right? Your update could make it easier for others working with older or custom trailers.
